I would like to know what is california's state's legal cut off level for a postive for meth on a blood immunoassay test in the drug labs.The first test results i had just stated postive did not state for what just said postive. I had a legal doctors perscription for amphetamines due to water in my ear. showed it to the court they did not care. I was arrested for under the influence.I am not gonna pled guilty for something i did not do. My second lab test came back 350 ml for amphetamines. I have read that the federal legal cut off level for a positve is 500-1000 ml. But can not find the legal limits in criminal courts. does anyone know? I stated to take to trial but the court will not supenoa my doctor they want me to plea guitly this case has been going to court for 9 months now. i want it dismissed.
